Tire tread



FIG. 1 is an isometric view, partially schematic, of a tire tread showing my new design, it being understood that the tread pattern repeats uniformly throughout the circumference of the tire tread, as indicated schematically in solid lines, and the opposite side being substantially the same as that shown; and,

FIG. 2 is an enlarged partial developed plan view thereof.

The broken line showing of the tire inner bead is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for tire tread, as shown and described.
